SMTP 错误 554 5.7.1 和 221 2.7.0

我有一台专用服务器，它连接到网络托管以使用 SMTP 协议发送邮件，但我收到 554 5.7.1 和 221 2.7.0 错误，并且无法发送电子邮件。完整的 SMTP 日志如下。

这是用 Perl 编写的发送电子邮件的脚本：

    my $mail = "mail.bellakabelky.sk";
    my $pass = "secret";
    my $user = "mail\@bellakabelky.sk";
    my $to = "tomsk.slovak\@gmail.com";

    use Data::Dumper;
    use Net::SMTP;
    use Mail::Mailer qw(sendmail);

    my $smtp = Net::SMTP->new(
                       Host => $mail,
                       Port => '25',
                       Hello => 'dev.bellakabelky.sk',
                       Timeout => 30,
                       Debug   => 1,
                      );
    print Dumper($smtp);
    $smtp->auth($user,$pass);
    $smtp->mail($user);
    $smtp->to($to);
    $smtp->recipient($to);
    $smtp->data();
    $smtp->datasend("To: Tomsk <$to>\r\n");
    $smtp->datasend("From: Mail <$user>\r\n");
    $smtp->datasend("Return-Path: $user\r\n");
    $smtp->datasend("Reply-To: $user\r\n");
    $smtp->datasend("Subject: Subject\r\n");
    $smtp->datasend("\r\n");
    $smtp->datasend("hello");
    $smtp->dataend();
    $smtp->quit;

我收到 554 5.7.1 和 221 2.7.0 错误。这是来自 SMTP 的日志：

我真的不知道问题出在哪里，我正在寻找解决方案，但没有找到任何东西。

完整性错误细目 -

Net::SMTP=GLOB(0x51d1810)>>> RCPT TO:<[email protected]>
Net::SMTP=GLOB(0x51d1810)<<< 554 5.7.1 <[email protected]>: Sender address rejected: Your mail account ([email protected]) was compromised. Please change your password immediately after next login and contact technical support.
Net::SMTP=GLOB(0x51d1810)>>> RCPT TO:<[email protected]>
Net::SMTP=GLOB(0x51d1810)<<< 554 5.7.1 <[email protected]>: Sender address rejected: Your mail account ([email protected]) was compromised. Please change your password immediately after next login and contact technical support.

发送收件人列表时，服务器会响应错误，这清楚地表明了问题所在。有趣的是，他们选择在此时响应错误，同时毫无问题地接受发件人地址，但这取决于他们。如果您想知道他们为什么认为该帐户被盗用，您需要询问邮件提供商。

Net::SMTP=GLOB(0x51d1810)>>> DATA
Net::SMTP=GLOB(0x51d1810)<<< 554 5.5.1 Error: no valid recipients

服务器在此处返回错误，因为您尝试发送邮件内容，但尚未设置任何收件人 - 给出的两个收件人均被拒绝。当没有接受收件人时，正确的邮件客户端将出错/断开连接，并且不会发送命令DATA。

Net::SMTP=GLOB(0x51d1810)>>> .
Net::SMTP=GLOB(0x51d1810)<<< 221 2.7.0 Error: I can break rules, too. Goodbye.

当您的客户端继续尝试向服务器发送数据时，尽管没有有效的收件人并且服务器已拒绝您的DATA命令，服务器也会做出尖刻的回应。
